We evaluated hepatic hemangiomas by free-breathing and high b-value DWI, and corresponding isotropic ADC maps to differentiate hemangiomas from cysts. Forty-five hemangiomas and forty-five cysts were evaluated. Forty-one hemangiomas (91%) showed high signal intensity, whereas all forty-five cysts showed iso to low signal intensity on DWI. The ADCs were 1.94 +/- 0.45 in hemangiomas, and 3.32 +/- 0.44 in cysts (0.0001>p). DWI may be useful for the diagnosis of hemangiomas in differentiation from cysts without the administration of contrast medium. The ADC values may be helpful for the diagnosis of hemangiomas which do not show high signal intensity on DWI.
